I have a mobile phone, of course - I think it would be silly not to have one - but only use it to phone for a taxi when I'm outand, very occasionally for some other reason.
This afternoon, the Electric Company have fitted one of those smart meters - at their expense and for their benefit! It won't make any difference to me. It has to be done before British Gas can fit their smart meter.
I was, however, most impressed to find that the Engineer was a young woman, so of course I congratulated her on her achievement.
